Abstract

With the expansion of current use and anticipated further increases in the use of mobile phones and other personal communication services, there have been considerable research efforts devoted to interactions between antennas on the human body. These activities are motivated by two factors: 1) a need to evaluate the antenna performance with the presence of the human body; and 2) a need to evaluate the rate of radio frequency (RF) energy deposition in the biological tissue, called specific absorption rates (SAR), in order to assess potential health effects and compliance with various RF exposure standards.

In this paper, a half human body with a cylindrical dipole antenna is simulated by using FEKO program for the analysis of SAR in the human body. The human body model is inhomogeneous and classified into only two kinds of material (average muscle properties for torso and upper arms and average brain properties for head and neck). The applied antenna is a cylindrical dipole antenna, operated at 900MHz frequency and radiated power of 0.12 watt. The purpose of this simulation is for calculation of 1g average SAR on the above system, which is recommended its limit value 1.6W/kg in FCC and ICNIRP. In addition to these results, 10g average SAR is calculated.

The obtained results show that the spatial-peak SAR values as averaged over 1 gram on the human model obtained with a radiated power of 120 mW are well below the limit of 1.6 W/kg.
